An object accelerates in a direction that is always perpendicular to its motion.

A gas is in a sealed container.Part ABy what factor does the gas temperature change if the volume is doubled and the pressure is

Goryan [66]

A) The temperature increases by a factor 6

We can use the ideal gas equation:

$pV=nRT$

where

p is the pressure

V is the volume

n is the number of moles

R is the gas constant

T is the temperature

We can also rewrite it as

$\frac{pV}{T}=nR$

The gas is in a sealed container - this means the amount of gas is fixed, so n is constant. Since R is constant too, the term on the right in the equation is constant. So we can rewrite the equation as:

$\frac{p_1V_1}{T_1}=\frac{p_2 V_2}{T_2}$

where in this problem we have:

$V_2 = 2V_1$ (the volume is doubled)

$p_2 = 3 p_1$ (the pressure is tripled)

re-arranging the equation, we find the change in temperature:

$\frac{T_2}{T_1}=\frac{p_2 V_2}{p_1 V_1}=\frac{(3 p_1)(2 V_1)}{p_1 V_1}=6$

so, the temperature increases by a factor 6.

B) The temperature increases by a factor 1.5.

We can use again the same equation:

$\frac{p_1V_1}{T_1}=\frac{p_2 V_2}{T_2}$

Where in this case:

$V_2 = \frac{V_1}{2}$ (the volume is halved)

$p_2 = 3 p_1$ (the pressure is tripled)

So, we can find the change in temperature:

$\frac{T_2}{T_1}=\frac{p_2 V_2}{p_1 V_1}=\frac{(3 p_1)(\frac{V_1}{2})}{p_1 V_1}=\frac{3}{2}=1.5$

So, the temperature increases by 1.5 times.

A thermionic tube with only a cathode and an anode is called?

Alenkasestr [34]

A vacuum tube consists of cathode (also called as filament), anode (also called as plate), and electrode (also called as grid). Cathode is an electron emitter that emits the free electrons whereas anode is an electron collector that collects the free electrons.
I hope this helps.

You drop an ice cube into an insulated flask full of water and wait for the ice cube to completely melt. The ice cube initially

3241004551 [841]

Answer: $T=12.69^{\circ}C$

Explanation:

Given

Mass of ice $m=60 gm$

mass of water $M=760 gm$

Initial Temperature of water $T_i=20^{\circ}C$

Let T be the Final Temperature of mixture

Latent heat of Fusion $L=334 J/gm$

heat required to melt ice completely is

$Q_1=60\times 334=20.04 kJ$

Heat released by water is taken by ice thus

$Mc_{water}(20-T)=mL+mc_{water}(T-0)$

$0.76\times 4.184\cdot (20-T)=20.04+0.06\times 4.184\cdot (T)$

$T=12.69^{\circ}C$
